Win 7 HP loses internet connection during "sleep"

I wake my Win 7 HP system each morning without its internet connection. It lost it sometime during sleep. It reestablishes the connection without any help from me but it takes most of a minute sometimes for that to happen. My system is hardwired to the cable connection through the modem and router.

I have Googled the behavior and found many posts that suggest opening the device manager, selecting "Power Management" in the properties of the network adapter and unchecking the boxes that allow the adapter to be powered off during sleep. That is an elegantly simple solution but my Power Management properties do not contain such an option for my Intel 82575 DC Gigabyte Network Connection.

Are there other options available to correct this behavior which has only recently begun?

Intel says says the driver are up to date; Windows agrees.

Make sure you've installed all rounds of Important and Optional Windows Updates, after enabling Automatically deliver drivers via Windows Update (Step 3). There may be a performance Update needed or a newer driver yet delivered.

Then work through these Sleep Mode Problems.

If the problem is only recent, try System Restore to before it happened.

If it persists go over your install more thoroughly using the Troubleshooting Steps for Windows 7

Just goes to show, when offering advice, start with the most basic and skip nothing.

Glad you were able to get your issue resolved.
